The present invention relates to a cold-resistant power control communication combination type high-voltage-resistant flat cable. The cable comprises three first wire cores distributed in rows, a second wire core is arranged between the neighboring first wire cores at one side, a multimode fiber is arranged between the neighboring first wire cores at another side, and the outside of the first wirecores, and the second wire core and the multimode fiber is collectively wrapped with a outer sheath. Each first wire core comprises a first conductor, a silicon rubber insulation layer, a first wrapping layer and a tin-plated copper wire shielding layer. The second wire core comprises a filling rod, two layers of second conductors, a second wrapping layer and a copper wire shielding layer. The filling rod comprises a wire rope and a butyronitrile material sheath wrapped at the outside of the wire rope. Compared with the conventional cable, the flat cable has more excellent cold resistance, high temperature resistance and distortion resistance, and the insulation tensile strength of the cable is also greatly improved, so that the cable can be adapted to the work under multiple complex environments, the internal mechanism of the cable is protected, the service life of the cable is prolonged, and the hidden danger of power transmission is effectively reduced.
